<li>Click on an element to display its components (metal ions or ligands).</li>

Point to a reaction product with the mouse, or select it with either the keyboard or
the mouse, to display information on the status line at
the bottom: reaction, equilibrium constant, and reference.</p>
<p style="line-height:2.5ex; margin-top:0.2ex; margin-bottom:0;">
You can remove a reaction by right-clicking with the mouse
(or pressing the &#147;Delete&#148; key if using the keyboard).

</li>
<li>Click on the menu &#147;File / Save and Exit&#148; to create an input file

<ul type="square">
<li>Within the periodic table you can move with:
<ul type="disc">
  <li>Up and Down arrow keys:
  move to next/previous row.</li>
  <li>&#147;Tab&#148;; Shift-&#147;Tab&#148; and Left and Right arrow keys:
  move to next/previous element.</li>
  </ul></li>
<li>The components-lists and the reaction-list have an underlined
  letter in the caption texts. Type <nobr>Alt-letter</nobr> to jump to that list.</li>
<li>The space-bar acts as a mouse button: <nobr>e.g.,</nobr> click on a component
  to selected it.</li>
<li>Menus have an underlined letter and they may be invoked by using
  the <nobr>Alt-letter</nobr> combination. For example select the menu
  <nobr>&#147;<u>F</u>ile&#148;</nobr> by typing <nobr>Alt-F.</nobr></li>
<li>The &#147;Tab&#148; and Shift-&#147;Tab&#148; keys will move the focus
  to different fields in all windows. &#147;Tab&#148; moves the focus in one direction
  (usually downwards) and Shift-&#147;Tab&#148; moves in the opposite direction.</li>
<li>To exit a window:
<ul type="disc">
<li><nobr>Alt-Q</nobr> and the &#147;Esc&#148; key are equivalent to a &#147;Cancel&#148; button (quit).</li>
<li><nobr>Alt-X</nobr> and <nobr>Alt-Enter</nobr> will
  exit any window: they are equivalent to an &#147;OK&#148; button.</li>
<li>If there are &#147;OK&#148; and &#147;Cancel&#148; buttons: push the space
  bar on the button (change the focus between buttons with the Tab or
  <nobr>Shift-Tab</nobr> keys).</li>
